Role of Rhythmic neuRal synchRonization in

A growing body of neuroimaging research has documented that, in
theabsenceof anexplicittask­theso-called"restingstate,"thebrain
exhibitsstructuredspatiotemporalpatternsof activity.Inparticular,
analysisof thefMRIbloodoxygenlevel-dependent(BOLD)fluctua-
tions (<0.1 Hz) during such conditions has revealed the existence
of consistent networks, called resting state networks (Biswal et al.,
1995).Among them,the so-called default-mode network is believed

2006). Although this network could be associated with daydream-
ing, free association, stream of consciousness, or inner rehearsal in
humans,similar patterns have been found in anesthetized monkeys,
demonstrating that this network reveals intrinsic properties of the
brain(Vincentetal.,2007).Since,aseriesof othernetworkshasbeen
